PARCEL-BUNDLING MACHINE.

Specification of Letters Patent.

Patented June 19, 1906.

- To all whom it may concern.-

Be it known that I, GEORGE HERBERT Ans- HEAD, a subject of the King ofGreat Britain *and Ireland, residing at 294 Stanstead road,

Forest Hill, London, S. E. England, have invented new and usefulImprovements in and Relating to Parcel-Bundlin Machines, :of

- which the following is a speci cation.

The invention relates'to improvements in bundling machine's of the typedescribed in my application for patent, Serial N o 182,922,

' filedNovember 27, 1903.

The'object of the invention is to modify the bundle-feeding mechanismsothat more time may be allowed for the insertion of the bundle or pile ofloose papers to'be bound.

, The invention consists, in a machine of the type indicated, in meansfor causing the main feeding-fingers to make substantially the whole oftheir return stroke in such a manner as not to interfere with theinsertion of'a fresh bundle or pile of papers. The invention alsoincludes means for closing the slots in the table through which the I ifeeding-fingers pass. Referring to the accompanying drawings",

which form part of this specificatlon, Figures 1 and 2 show plan and endview of the feeding-fingers and vertical slides.

" detail of the spring-retaining catch.

Where desirable, the same reference-symbols have been used in thedifferent drawings to denote corresponding parts.

In carrying the invention into effect ac-' cording to one form thefeeding-fingers 3 are adaptedto pass through slots 2 in the table 1,carried by the frame a. These fingers pass through slides b, relativelyto which they are capable of an up-and-down movement. The slides 12 areattached to a cross-bar c, this cross-bar carrying brackets (1, adaptedto be reciprocated by the connecting-rod 6 and crank 7 on the slide-bars5, as in the patent above referred to. times for convenience form theslides 12 and the brackets d in one piece. gers 3 are provided at theirlower ends with the runners or rollers e, as shown. a In order to givethe feeding-fingers 3 the desired up- I may some- The feeding fim'and-down movement, according to oneform (see Fig. 3) I. arrange top andbottom horizontal guides f and g, respectively, and inclined guides h'11, running in an upward direction from the -'ends of the bottom guidesg, the former of these inclined guides being hinged. I also arrangeother inclined guides k, pivoted or hinged to one end of the topfunction of these cams being by their motion to transfer the rollerswithout shock to the guides h, hinged at their lower ends to 'allow forthepassing of those parts of the cams more distant from their axes, theguides h being re turned by any suitable springs or the like. Thefeeding-fingers are in this way lowered beneath the level of the table1, in which posi tion they make their return or non-operative stroke,the rollers being then supported by the bottom horizontal guides g.Toward the end of the return stroke the rollers pass along theupwardly-inclining guides?) and during this part of their movement pushpast the hinged guides 76. Finally at the commencement of the workinstroke the rollers pass up these hinged gui es 7a (which have meanwhilefallen back against suitable stops) onto the top horizontal guides f,the cycle of operations above described bein then repeated. In thismanner the feedin gers are below the level of the table for a argeproportion of their return stroke, thus affording more time for theplacing in position of a fresh bundle of papers.

According to a modified form of the invention (see Fig. 4J1 dispensewith the various guides described above and use levers n, fulcrumed, forexample, on the shaft 45. These The I levers are each provided with along and short arm, the long arms having at their ends suitable surfaces0 to receive the rollers. The shorter arms are weighted to such anextent as to overbalance the long arms, together with thefeeding-fingers carried by them. A

disk r or the like carrying a pin sis adapted to engage the short end ofeach lever, respectively, in a manner to be hereinafter described. Thesedisks may be mounted, for example, on the shaft 8 but any other suit- 5able positions of the lever fulcrums and disks may be adopted. Theaction of this form of my invention is as follows: At the end of thereturn stroke of the feeding-fingers the shorter ends of the levers nare released by the pins 8 and fall, owing to the manner in which theyare weighted, thus liftin the feeding-fingers. The working or forwarstroke then beginning, the feeding-fingers are transferred to thecarriers t, which are pushed along the guides 5 by the advance of theslides b, a bundle being thus fed forward into the com- .pressingposition. The first few inches traversed during the return strokesuffices to withdraw the feeding-fingers from the support afforded bythe carriers, the feeding-fingers thereupon falling by their own weight.Any suitable spring-buffer or the like is provided to take up the shockof the fall. A lug, such as a, forming part of each feeder-arm,respectively, then rests on the top of the slide 1), in which positionthe greater part of the return stroke is completed. Toward the end ofthe return stroke, however, the pins 8 escape from the short ends of thelevers, which they have in the meantime raised, thus allowing theweights to raise the feeding-fingers again to their working position,when the above cycle of operations is repeated. It will be seen that thecarriers t are returned by the hooked pieces 4), attached to the slides6. According to yet another modification, which I prefer to those abovedescribed on account of its greater simplicity, (see Figs. 6, 7, and 8,)I mount a chain-wheel 9 rigidly on the crank-shaft 8 and connect this bya chain to a similar wheel 10, which I mount loosely on its shaft. Alink 11, pivoted at one end to the chain-wheel 10 serves to transmitmotion from the latter by way of the lever 12 to the rocking shaft 13,on which the levers 141, slotted at their free ends, are mounted. Theseslots engage, respectively, with pins 15, mounted on the carriers 16,adapted to slide in the fixed guide-bars 17, the rollers e of thefeeding-fingers 3 being adapted to rest on these carriers while liftingtakes place. I wish it to be understood that in order to show thedifferent parts of the mechanism as clearly as possible the chain-wheels9 and 10 are not represented as set in their correct relative workingpositions. I preferably arrange these so that lifting of thefeeding-fingers commences before the crank has reached the dead-point atthe end of its non-feeding stroke and ends more or less symmetrically onthe other side of this dead-point. The whole lift is thus effected Witha minimum traverse along the guide-bars 5. In order to prevent return ofthe feeding-fingers when 65 lifted into their Working position, Iarrange a catch or pawl 18 (see Fig. 9 pivoted to each of the slides 19and pressed by the spring 19 to enter a notch in the feeding-fingers 3.At the end of the feeding-stroke a tailpiece 20, attached to this pawl,abuts against any suitable stop, thus releasing the feeding-fingers,which then fall by their own weight. The action of this modificationwill be readily understood in view of the foregoing description withoutfurther explanation. The invention also includes means such asadjustable bars, stri s, or the like for closing the slots 2 in the tabe through which the feedin -fingers pass.

According to one form, as shown applied to the feeding mechanism of Fig.4, the slotclosing device may consist of strips w, checked into theedges of the slot, as shown in cross-section in Fig. 5, the strips beingattached to the slides I), or according to a modification flexible bands51:, made, for example, of leather, or similar to those used formanufacturing bandsaws, may be employed, these strips being likewiseattached to the slides b and held taut by weights ,2 or other suitabletension device, as seen in Fig. 4.

In some cases I may close the slots by moving strips thereover in adirection at right angles to the movement of the feederarms.Slot-closing devices of the nature described are preferably arrangedboth. in front of and behind the feeding-fingers.

I have found when developing the underlying idea ofmy inventionviz., themodification of the feeding-gear shown in my previous patent so as toobtain more time for the insertion of a fresh bundlethat it may beembodied in a variety of different mechanisms. The examples which I havegiven, how ever, of which I consider that shown in Figs. 6, 7, and 8 themost satisfactory, sufficiently indicatethe scope of my invention.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In combination in a machine of the class described, a table, abracket reciprocating beneath the same horizontally, feed-fingersslidable vertically through the said bracket and means controlling theelevation of the feed-fingers in respect to the table whereby they willbe projected above the same for the feeding stroke and will be loweredfor the return stroke, substantially as described.

2. In combination in a machine of the class described, a feeding fingermovable vertically in relation to the table or surface over which thematerial is to be fed, and means for lowering the said feed-finger onits return stroke to avoid contact with the material, said meansincluding a lifting-lever, substantially as described.

3. In combination in a machine of the class described, a feeding -fingermovable vertically in relation to the table or surface over which thematerial is to be fed, and

' "means ior lowering the said feed-finger on its return stroke to avoidcontact With the material, said means including a lifting-lever andmeans for holding the finger up and adapted to be disengaged therefromwhen a certain position'is reached, substantially as described.

4. In combination in a machine of the a tion to the table, means formoving the feedfingers along the talble, a table slotted for saidfingers and means for closing the slots along which the feeding-fingerspass, substantially as described.
